Sanitary cartridge filter housing

Abstract

A sanitary cartridge filter housing is formed by a bottom plate having a raised platform thereon from which a splash plate extends radially. A housing cylinder is mounted on the bottom plate and clamped thereto, with an O-ring therebetween, by a surrounding clamp. At an opposite end of the housing cylinder is located a top plate which is either held in place by a clamp or by the pressure exerted on the top plate by a tightening nut threadingly engaging a winged center post with the threads of the winged center post engaging the tightening nut externally of the formed housing. The winged center post is solid (non-perforated) and extends through the center of the housing cylinder, through the platform supporting the splash plate, and is secured at its lowermost end at the bottom of an outlet port tee located externally of the formed housing.

I claim: 
     
       1. A filter housing comprising: a bottom plate,   a top plate,   a cylindrical wall member extending between said bottom plate and said top plate,   said bottom plate, said top plate and said cylindrical wall member defining a fluid tight cavity having a cavity inlet,   an outlet opening formed in said bottom plate,   a central post extending through said top plate and into said outlet opening for supporting a filter element, and   means for securing said bottom plate, said top plate and said cylindrical wall member together to form said liquid tight cavity for transfer of liquid from said cavity to said outlet opening,   said means for securing including a threaded end of said central post extending above said top plate and externally of said liquid tight cavity.   
     
     
       2. A filter housing as claimed in claim 1, wherein said means for securing includes another end of said post opposite to said threaded end terminating below said bottom plate within a T-shaped pipe. 
     
     
       3. A filter housing as claimed in claim 2, wherein said another end of said post is secured to a cap sealing one section of said T-shaped pipe. 
     
     
       4. A filter housing as claimed in claim 1, wherein said means for securing includes a nut threaded onto said threaded end of said post. 
     
     
       5. A filter housing as claimed in claim 1, wherein said top plate, said bottom plate and said cylindrical wall member are made of stainless steel. 
     
     
       6. A filter housing as claimed in claim 1, wherein said post is solid. 
     
     
       7. A filter housing assembly for sanitary filtering of liquids, said filter housing comprising: a bottom plate having an outlet opening,   a top plate having a post opening,   a cylindrical wall member secured to said bottom plate and said top plate in a liquid tight manner to form a filter cavity having a cavity inlet,   a central post extending through said post opening and into said outlet opening to secure said cylindrical wall member, said bottom plate and said top plate in said liquid tight manner, a threaded end of said central post extending above said top plate and externally of said filter cavity, and   filter means having a central opening being mounted on said central post for sealingly engaging said top plate around said post opening and sealingly engaging said bottom plate about said outlet opening for passage of liquid through said filter means to said outlet opening.   
     
     
       8. A filter housing assembly as claimed in claim 7, wherein another end of said post opposite to said threaded end terminates below said bottom plate within a pipe connected to said outlet opening. 
     
     
       9. A filter housing assembly as claimed in claim 8, wherein said threaded end of said post is secured within said pipe connected to said outlet opening. 
     
     
       10. A filter housing assembly as claimed in claim 7, wherein a nut is threaded onto said threaded end of said post. 
     
     
       11. A filter housing assembly as claimed in claim 7, wherein said post is solid. 
     
     
       12. A filter housing assembly as claimed in claim 7, wherein said top plate, said bottom plate and said cylindrical wall member are made of stainless steel. 
     
     
       13. A filter housing assembly as claimed in claim 7, wherein said post is of a lesser width than said outlet opening. 
     
     
       14. A filter housing assembly as claimed in claim 7, wherein said post includes means for positioning said filter means.
